BAGKBAND Hook.

Application inea June. 2o, 11925]- seiiai No. 38,504.

rIhis inventionrelates to buckles and clasps particularly designed foruse in c onnection with harness and has for its object the provision ofa novel device adapted for use in connection ywith the back band, theconstruction and arrangement being such that there will be an automatic'clamping action which will hold firmly, the holding action increasingautomatically in accordance with the strain exerted upon the backv band.

An important object is the provision of a device of this character whichis so con structed and arranged that upon slight baclrward movement ofthe back band the clamping member will be released so that disengagementof the back band from the device may be very easily effected withoutbeing necessary to pry the parts loose as is the case with the ordinaryconstruction.

Another object is the provision `ofa device of this character having` ahook with which a chain or the like may be connected, the hook being sopositioned with respect to the back that chaf'mg of the animal will beprevented.

An additional object is the provision of a device of this characterwhich will be simple and inexpensive in manufacture, easy to use andadjust, positive in action, efficient and durable in service, and ageneral imrovement in the art.v Y With the above and other objects andadvantages in view, the invention consists in,

the details of construction and arrangement of parts to behereinaftermore fully described and claimed,and illustrated in the accompanyingdrawings, infwhich z- Figure 1 is perspective view of the device showingit associated with a back band.

Figure 2 is a longitudinal section.

Figure 3 is a detail cross-section taken on the line 3-3 of Figure 2.

Referring more particularly to the drawings, I` have shown from a singlepiece of sheet metalwhich may be cut and bent to shape so it will, ofcourse, be understood that if desired the deV- vice -could be formed asa casting. The device includes a body portion 1() which is of elongatedplate-like formation and which is provided near its ends with slots 11and 12 and near its central portion with an intermediate slot 13. Theback band designated by the letter A is threaded through the vportionbeneath the same.

my device as formed.

slot androne portion thereof will therefore lie above'the body member 10and the other ber 10 is formed .to provide spaced upstanding sideflanges 14 formed with inclined slots 15 through whi-ch are engaged thereduced end portions or tongues 16 of an angular clamping plate 17,which has one edge provided with .a plurality of teeth 18 adapted tobite into the back band for maintaining the holding action. The eX-tremities of the tongues 16, that is, outwardly of the side flanges .14are upset or with retaining lips 19 which will prevent the clampingplate lfrom disengagement from the remainder of the device. The backband, o f course, passes between the toothed edge Vof the clamping plate17 and the intermedi ate portion of the plate member 10 and it is quiteevidenced that when strain is applie to the back band its engagementwith the clamping member will tend to slide the latter along theinclined slot 15, this naturally automatically increasing the holdingaction sp that slippage will be positively prevented.

Near the slot 11, the plate or body member 10 is cut as indicated at 20,21 and 22 and the material within the confines of these cuts is struckout to define a hook 23 upon which a chain or the like may be engaged.The chain will naturally be disposed loutwardly of and lie upon the backband so that chafing of the animal will be positively From the foregoingdescription and a study of the drawings it will be apparent that I havethus provided a simply constructed, inexpensive and very `easilyoperated device for the purpose specified which will have thev greatadvantage of increasing its clamping action automatically 1n accord-'ance with the strain imposed upon it. Furthermore, it is quiteevidenced that whenever it 1s desired to disengage the back bandy fromvthe device it is merely necessary to ply the former in such a directionas to cause the clamping plate 17 to ride upwardly along the slotlwhereupon the teeth 18 will be disengaged from the back band permittingthe latter to be withdrawn or loosened as the case may be.
